NAME

       ubertooth-dfu - Device firmware update for Ubertooth

SYNOPSIS

       To update firmware, run:

              ubertooth-dfu -d bluetooth_rxtx.dfu -r

DESCRIPTION

       ubertooth-dfu(1) is a utility for updating firmware on Ubertooth. It can also download the
       currently running firmware from the device.

       Running the upload or download command automatically resets the device into  the  firmware
       update bootloader. The USB ID of the Ubertooth will change in the bootloader, and this may
       cause problems when attempting to update firmware from inside a VM.

       In the DFU bootloader, the TX, RX, and USR LEDs will turn on and off in sequence. If  this
       does  not  occur,  you  can  try to manually force the device to boot into the bootloader.
       Refer to [MANUALLY ENTERING BOOTLOADER][].

OPTIONS

       Major modes:

              • -d <firmware.dfu> : Download - write DFU file to device

              • -u <output.dfu> : Upload - read DFU file from device

              • -r : Reset device after performing operation

       Miscellaneous:

              • -s <file.bin> : Add DFU suffix to binary firmware file

              • -U <0-7> : Which Ubertooth device to use

MANUALLY ENTERING BOOTLOADER

       If the device does not enter the bootloader when running the upload or download  commands,
       it  is  possible to force the device to boot into that mode when it is inserted. To do so,
       you will need to jumper two pins on the expansion header.

       The expansion header is a 2x3 pin header between the two largest chips on the board, about
       halfway  between the USB connector and antenna. It is labeled "EXPAND" on the back side of
       the board. Holding the board so USB is pointed up, on the front  side  of  the  board  the
       expansion header looks like this:

                +-------+
              6 + O | O | 3
                +---+---+
              5 + O | O | 2
                +---+---+
              4 + O | X | 1
                +---+---+

       PIN #1, marked X, is square.

       With  Ubertooth  unplugged,  use a piece of wire, paperclip, staple, etc to connect pins 1
       and 2 together. When it it plugged in, the Ubertooth should enter  bootloader  mode  (LEDs
       will be turning on and off in sequence).

       The bootloader will exit after 5 seconds of no activity and boot into the main firmware.
